We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).

The core background report we provide (including basic information, mileage verification, and accident investigation conclusions) supports both Chinese and English outputs to ensure that overseas buyers or your end customers can read it without barriers.

Of course. Our system supports single unit orders. However, objectively speaking, the shipping booking fees, documentation processing fees, and customs clearance fees for a single vehicle are very high. We recommend that individual buyers calculate the total landing cost before making a decision.
